- Disable preemption (
get_cpu()
). - Shared memory is per-core. We only need to disable the preemption to prevent the shared memory of current CPU from being corrupted by the other tasks.
- Issue SBI call:
SBI_EXT_MPXY_READ_ATTRS
to read the attribute. - If successful, copy the attribute from the shared memory to the buffer.
- Enable preemption (
put_cpu()
).
